1 Claim.

' This invention relates in general to a windmill construction and is particularly concerned with novel means for lubricating its various moving parts. The present invention is a division of my copending application for patent for a Guide head, filed January 15, 1930, U. S. Serial No.

It is an object of this invention to provide improved means whereby the guide head and other moving parts of the Windmill will be automatically and efiiciently lubricated.

It is a further object of this invention to provide an improved lubricating system for windmills. which is so designed that oil will be carried upwardly along the guide rods for the cross It is also an object of this invention to provide in a windmill construction, improved means for lubrication of the pitman connection to the cross head.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claim.

In the accompanying drawing, which illustrates a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the difierent views:

Figure 1 is an enlarged plan view of a windmill cross head with which my present invention is adapted to be used.

Figure 2 is a plan View of the cross head showing its connection to the driving mechanism of my windmill construction, and means for collecting and distributingthe lubricant to the various moving parts associated with the cross head.

Figure 3 is a fragmental elevational view partly in cross-section showing the details of the lubricating system for the cross head, taken substantially on line IIIIII of Figure 2.

Figure 4 is a fragmental end elevational view of the guiding mechanism and lubricating means. As illustrative of this invention, there is shown a casing 10 for housing the mechanism for drivr ing the pump rod. In this instance, a standard March mountedforreciprocable movement. The upper portion of this passageway is provided with an upwardly'extending hub or collar'15 for'preventing leakage of the lubricant'from the basin into the pump rod bore. A pair of spaced guide rods 60 16 and 17 are arrangedoneachside of the pump rod and are threadedly secured within the lubri-- cant basin to the standard 11'. The guide rods are maintained in parallel spaced relationship by means of a cross piece-18 which extends between the upper ends thereof. This cross piece may be secured to the guide rods in any well-known manner.

A cross head His threadedly securedatits lower extremity to the pump rod, and comprises guide rollers 20 and 21 which are journalled re-' spectively upon the shafts 22 and 23which extend through and are supported by the'body portion of the cross head 19. Each guide roller is provided with a peripheral groove 24 which is formed to receive a vertical guide rod-therein. It is to be noted that the axis of rotation of each roller as thus mounted is at right angles to the plane established by the guide rods, and. also the guide rollers are arranged on the outside of the guide rods. With this construction, both rollers may roll against their respective guide rods. Con- .sequently, if the cross head should twist, the rollers would still be capable of rolling and no objectionable abrasive action upon the guide rods would occur because there would always-be a rolling action between both rollers and their respective guide rods. Further, as arranged, the thrust of the'pitman in operation will be directed in the plane of the guide rods so as to avoid I twisting the cross head.

A shaft 25, which extends parallel to the axis of rotation of each guide roller, is journalled midway-between the guide rollers in bearings 26 9 and 27 which are integrally formed with the body portion of the cross head 19. Reciprocable movement is imparted to the pump rod by means of gears 28.which are rotatably mounted upon the standard 11 so as to run in oil and operate in 100 a plane on each side of the guide rods in spaced relation thereto. The gears 28 form crank mem bers to which one end of each pitman 29 is connected. The other ends-of the pitman are respectively connected to the ends of the shaft 105 which, it will be noted, extends parallel with the rollers so that the thrust of the pitman will be directed substantially in a plane passing through the guide rods, thuswise avoiding any'tendency to twist the cross head. The gears 28 are driven by a pair of pinions in mesh therewith, said groove 2% to the axis thereof.

pinions being, connected to a driving shaft 31 which is journalledin any approved manner in the casing 10. The shaft 31 carries at one end a wind-wheel, not shown in the drawing, of WellknoWn construction. I

The lubricating means for oiling the moving parts of the windmill construction includes a spiral member 32 of wire or the like which surrounds each guide rod. The upper end of each member 32 is loosely connected to the cross head 19 in such a manner that the coil of wire will be suspended below the guide head and will be moved along the guide rod as the pump rodreciprocates. When the pump rod has reached its lowest point of travel, the spiral coil of-wire will dip into'the lubricant in the lubricant basin, and, with the upward movement of the pump rod, the coiled wire will act as a conveyor to distribute the oil contained thereon along the uide rod. Each of the guide rollers is provided with a radial aperture 33- which extends from the It, is, therefore,

In order to lubricate The plate 34 will, therefore, be carried by the cross head during the reciprocable movement thereof, and the walls of the aperturesthrough which-the guide rods pass will skim or pick up a portion of the lubricant which has been dis-- This invention, therefore, provides an improved windmill construction having novel means for automatically oiling the cross head rollers, guide rods and pitman connection to the cross head, I

whereby a 'sufficient amount of oil is at all times supplied to these parts.

I am aware that many changes may be made and numerous details of construction may be varied through a'wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior JOHNAUGUSTI LUND.
